broadcast safe refers to a video signal that conforms to a given regional broadcast specification. It sets specific voltage levels for the blacks and whites of a video image, as well as the colors that can be accurately represented in the broadcast signal. Different specifications exist for different regions and formats. Broadcast safe specifications include standards for both audio and video formatting.
Color grading and non-linear editing software include waveforms and vectorscopes to analyze an image for broadcast safe compliance, as well as tools to adjust or clamp images in violation of the standards.
